Putting your display to sleep stops the video signal to any internal and external displays. For Apple displays and built-in displays, this also means that the backlight on the LCD is turned off to save energy.
When your display goes to sleep, the screen goes dark or turns off, but apps that are still busy on your Mac stay active. If your display has a power indicator, it may change to indicate that the display is in low-power mode. To wake your display, move the mouse, touch the trackpad, or press a key on the keyboard.
Put hard disks to sleep when possible

Consider deselecting this option if you have an internal or external non-SSD drive and you use apps—for example, pro audio or video editing software—that work better with continued read and write access to the hard disk.
Wake for network access

Other sleep modes
Some Mac computers enter special sleep modes when you leave them idle for a long time, helping them conserve even more energy.
Standby Mode
For Mac computers that start up from an internal SSD, macOS includes a deep sleep mode known as Standby Mode.

During standby, the state of your session is saved to flash storage (SSD). Then, the power turns off to some hardware systems such as RAM and USB buses.
Standby extends how long a notebook computer can stay asleep on battery power. A notebook with a fully charged battery can remain in standby for up to thirty days without being plugged in to power.
